1 Claim.

to the bars in the approximate center of the grille as a utilitarian aswell as an ornamental feature.

Another object of the invention is to provide an arrangement as setforth whereby the device attached yto the grille will assume the desiredposition when the grille is expanded or contract-ed to conform to anopening, depending upon the manner or position in which it is originally applied to the grille.

With the foregoing objects as paramount, the Y invention has particularreference to its salient features of construction and arrangement ofparts which will become manifest as the descrip'- tion proceeds, takenin connection with the accompanying drawing, wherein:

Figure 1 is a front elevational view of the invention, showing thegrille expanded and the i attached device in dotted lines,

Figure 2 is a fragmentary View of the grille contracted, showing theattached device in solid lines and its manner of changing positions whenthe grille is contracted, and

Figure 3 is another fragmentary view of the grille, showing a mail boxasan attached device.

Continuing with a moreY detailed description of the drawing, it is firstpointed out that the most popular type of grille is the intercrossed bartype in which the ends of the bars are curled, such as shown inapplicants co-pending application, Serial Number 204,182, now Patent No.2,210,371 issued August 6, 1940. This type of grille, however, has noprovision for the application thereto of a name plate or other suchdevice other than by perforating the bars to ren ceive screws or rivetsfor holding the attachment. It is obvious that to attach a device tosuch a grille would render the latter incapable of adjustment as tolength and width, the rivets restraining reiative movement of the bars.

'I'he present invention provides for the attachment to the bars of thegrille any desired form of device without hindering lateral or verticaladjustment of the grille by restricting or preventing relative pivotalmovement of the intercrossed bars constituting the same.

Accordingly, l designates obliquely disposed bars arranged to intercrossbars 2, each being pivoted to the other at a, in the form of a toggle.However, there is provided in the present case a pair of axially alignedintermediate bars 3, similar in all respects to the bars l and 2 withthe exception that the bars 3 terminate at b near the center of thegrille and on opposite sides of the central corresponding bar, at whichpoint they are perforated as at c. At the outer ends of each bar thereis provided aV scroll or curl 4.

At the top of the grille, a horizontal arrangement of bars 5 isprovided, adjustable to conform to the effective width of the grille,each bar being provided with an end scroll 6 which is riveted to thesides of the opening in which the grille is installed.

The horizontal bars are secured to the grille by close fitting collarsl, the latter also securing the decorative-member 8 to the grille. Thisarrangement affords a means to prevent Whipping of the upper scrolls ofthe grille and forms the .subject matter of the above identied c0-pending application.

Returning to the subject of the present invention, it will be observedthat a name plate 9 is pivoted at the points c to the inner perforatedends b of the bars 3 and at d to the central bar I midway of its ends.

In Figure 3, a mail box l 0 is mounted in a manner similar to that justdescribed.

It is apparent that before attachment of the plate 9 in the mannerdescribed, each bar section 3 may be swung independently of all otherbars about the pivot a. Also, before attachment of plate S, bar section3 may be subjected to a movement of translation which will cause thegrille to assume rhomboidal shape. After plate 9 is attached, the pivotsallow movement of bar sections 3 whichwill cause all members to move tostill another outline, thus providing greater adjustability thanheretofore possible.

It is apparent from the foregoing that a grille such as described may besold to a purchaser who may select his own device for attachment to thegrille, and when attached in the manner provided for, adjustment of thegrille either horizontally or vertically is not interfered with in anymanner as would be the case were it not for the provision of therelatively short bars 3, perforated as they are for the reception ofrivets for retaining the device 9.

It is to be noted that the device 9 is first seassume the desiredposition when the grille is adjusted to a position in'xed relation to anopening.

Manifestly, the construction as shown and described is capable of somemodification and such modification as may be construed to fall withinthe scope and meaning of the appended claim is also considered to beWitlin the spirit and intent of the invention.

What is claimed is:

A grille for screen doors and other openings comprising in combination,two sets of relatively spaced bars, the bars of one set intercrossing.rthe bars of the companion set, each bar of one set being pivoted to theintercrossing bars of the cured to the grille .in 'such a position thatit will companion set at each intersection; a` pair'of axially alinedbars supplanting the` intermediate bar of one set, each having asinglepivotal connection intermediate its ends to apoint intermediatethe ends of bars of the companion set and Whose inner and outer ends aredisplaceable rel-- ative to the remaining bars of their set and tothebars of the' companion set, the inner ends of said pair of barsterminating on either side of" the corresponding bar of the companionset and; utilitarian means pivoted to the inner ends of saidcomplementary bars and to a point midway between the ends of saidcorresponding barr whereby to be movable independently of the com--panion bars of said grille.
